36.0 g/t Gold Over 10.0 Meters - Froome Mine Life Extended With Discovery of New High-Grade Mineralization
McEwen (NYSE: MUX) has announced a significant discovery of high-grade gold mineralization approximately 200 meters West of the Froome Mine at its Fox Complex. The highlight intercept returned 36.0 g/t gold over 10.0 meters, including 160.0 g/t gold over 2.2 meters.
The Froome West mineralization consists of several sub-vertical, stacked mineralized lenses, similar in style to the Black Fox deposit. The mineralization remains open to the West and at depth, with mining infrastructure development already underway on four levels. The discovery's geology and mineralization style are comparable to the nearby Black Fox Mine, which historically produced nearly 1 million gold ounces down to 800 meters depth.
McEwen (NYSE: MUX) ha annunciato una scoperta significativa di mineralizzazione aurifera ad alta qualità a circa 200 metri a ovest della miniera Froome nel suo Fox Complex. L'intercettazione più rilevante ha restituito 36,0 g/t di oro su 10,0 metri, inclusi 160,0 g/t di oro su 2,2 metri.
La mineralizzazione Froome West è costituita da diverse lenti mineralizzate sub-verticali e sovrapposte, simili per stile al deposito Black Fox. La mineralizzazione rimane aperta verso ovest e in profondità, con lo sviluppo delle infrastrutture minerarie già in corso su quattro livelli. La geologia e lo stile di mineralizzazione della scoperta sono comparabili a quelli della vicina miniera Black Fox, che storicamente ha prodotto quasi 1 milione di once d'oro fino a una profondità di 800 metri.

McEwen (NYSE: MUX) hat eine bedeutende Entdeckung von hochgradiger Goldmineralisierung etwa 200 Meter westlich der Froome-Mine in seinem Fox-Komplex bekannt gegeben. Der herausragende Bohrabschnitt ergab 36,0 g/t Gold über 10,0 Meter, darunter 160,0 g/t Gold über 2,2 Meter.
Die Froome West-Mineralisierung besteht aus mehreren subvertikalen, übereinanderliegenden mineralisierten Linsen, ähnlich dem Stil der Black Fox-Lagerstätte. Die Mineralisierung bleibt nach Westen und in der Tiefe offen, wobei bereits der Ausbau der Bergbauinfrastruktur auf vier Ebenen im Gange ist. Die Geologie und der Mineralisierungsstil der Entdeckung sind vergleichbar mit der nahegelegenen Black Fox-Mine, die historisch fast 1 Million Unzen Gold bis zu einer Tiefe von 800 Metern gefördert hat.

Insights
McEwen's high-grade Froome West discovery extends mine life with exceptional 36 g/t gold over 10m, showcasing significant expansion potential.
McEwen's discovery at Froome West represents a significant high-grade gold intercept that will meaningfully extend the life of their Fox Complex operations. The headline intercept of
The geology at Froome West shows striking similarities to the nearby Black Fox deposit, which historically produced 1.1 million gold ounces and extended to 800 meters depth. This geological parallel suggests substantial exploration upside, especially since the current mineralization model only extends to 250 meters and remains open both laterally and at depth.
From a mining perspective, several technical aspects enhance the economic potential:
- The sub-vertical stacked mineralized lenses configuration typically allows for mining flexibility and potentially lower development costs
- The property can leverage existing infrastructure from current Froome Mine operations
- The presence of visible gold typically correlates with higher metallurgical recoveries
- The high-grade plunge measuring 15-25 meters wide provides a concentrated mining target
Most importantly, this discovery provides operational continuity between the current Froome production and the planned Stock Mine production (expected 2026). For a mid-tier producer like McEwen, bridging these production periods with high-grade ore significantly improves cash flow projections and reduces execution risk in their mine plan.
With infrastructure development already underway on four levels extending from existing workings, McEwen can rapidly integrate this discovery into production with minimal capital expenditure, potentially accelerating the timeline to first ore from this zone.
TORONTO, July 23, 2025 (GLOBE NEWSWIRE) -- McEwen Inc. (NYSE: MUX) (TSX: MUX) (“McEwen”, "MUX" or the "Company”) is pleased to announce the discovery of high-grade mineralization approximately 200 meters West of the Froome Mine, which is the current source of production at the Fox Complex. This discovery will extend our mining at Froome.
Highlights from Drilling at Froome West:
Intercepts along the Froome West high-grade plunge (refer to Figures 2 and 3):
- Hole 25PR-G424 returned 36.0 g/t gold over 10.0 m (including 160.0 g/t gold over 2.2 m), and 9.3 g/t gold over 7.8 m.
- Hole 25PR-G399 returned 6.7 g/t gold over 3.4 m.
- Hole 25PR-G381 returned 15.0 g/t gold over 6.6 m and 4.9 g/t gold over 2.2 m.
Extending mineralization further West (refer to Figures 2 and 3):
- Hole 25PR-G390 returned 11.7 g/t gold over 2.4 m and 18.5 g/t gold over 0.5 m, representing drill intercepts of two of the stacked mineralized zones stepping out to the West.
- Hole 25PR-G413 returned 22.1 g/t gold over 1.8 m.
Unless specified as core widths (CW), all assay intervals in this press release are presented as true widths (TW).
The mineralization we see at Froome West occurs as several sub-vertical, stacked mineralized lenses which can often lead to increased flexibility during mining. Within these lenses we are seeing a concentration of high grade in a roughly 15 to 25 meters wide, vertically oriented trend (or plunge). Gold mineralization remains open to the West and at depth, which encourages further exploration in both directions.
Froome West mineralization is similar in style to that seen at the Black Fox deposit (approx. 900 meters to the East and shown in Figure 1), characterized by structurally controlled, stacked, sub-vertically dipping quartz-carbonate veins, with occurrences of visible gold (VG) and showing a steep high-grade plunge. Total historical production at the Black Fox and Froome mines is 1.1 million gold ounces. The exploration program at Froome West will continue drilling to test deeper (along the down-dip extension of the high-grade plunge), and laterally (westward along strike), to evaluate broader regional mineralization trends.
Figure 1 below provides an aerial view showing the location of the Froome West mineralization in relation to the Froome Mine deposit currently being mined and the historic Black Fox Mine, including its open pit and underground workings. Future mining activities at Froome West will continue to use the existing infrastructure currently used for mining operations at the Froome Mine.

Mining infrastructure development on four levels is planned and already underway at Froome West, starting from the existing workings at the producing Froome Mine and extending 200 meters toward the West zones. This is shown in blue in Figures 2 and 3. The new infrastructure will allow for access and testing for extensions of the Froome West mineralization.

This discovery of high-grade mineralization will extend the mining at Froome and provide more optionality in our mine plan for the Fox Complex. As mentioned in previous announcements (see our June 5th press release and the Annual Meeting presentation from June 19th, 2025), our Stock Mine is part of the mine plan for the Fox Complex and is expected to come into commercial production in 2026.
“We are excited at the potential of what Froome West holds, in an area of our property that is relatively underexplored; our current mineralization model extends to a depth of 250 meters and remains open both at depth and to the West. The nearby Black Fox Mine historically produced nearly 1 million gold ounces, from mining that extended down to 800 meters below surface. With geology and mineralization styles comparable to those seen at Black Fox, which encountered mineralization as deep as 1,000 meters, the Froome West area has the potential to lead us to the discovery of a deposit of similar scale and significance,” said Chief Geologist Rob Glover.
